コッター バルブ

Specifying this valve spring means that you are buying a spring made in Japan to high quality control standards.

Specifying these springs means you are fitting the same springs that were deemed good enough by the factory when your machine rolled off the production line.

Renewing the valve retention cotters (or collets as they are sometimes referred to) at the same time is a sensible precaution!

• Using cheaper parts could be very costly!
• Consider replacing the outer spring at the same time!
